Abstract: A method and system to reduce a probability of incorrect interruption of an uplink transmission of a wireless device are disclosed. According to one aspect, decoding of a sequence of bits obtained from a signal received by the wireless device is performed without knowing whether the sequence corresponds to one of a grant for uplink transmission and noise. Decoding of the sequence of bits is performed to determine a probability metric associated with a first m bits of the sequence, where m is an integer greater than 1. The probability metric is compared to a threshold. The received signal is interpreted as having a grant sequence if the probability metric is greater than the threshold. The received signal is interpreted as noise if the probability metric is not greater than the threshold.

Abstract: A method and system for synchronized switching of a Transmission Time Interval (TTI) between at least two different TTI length values. A UE 100 transmitting a power report, where a control node 150 or a Base Station 110A evaluates the report and decides, based on the evaluation to order the UE to switch to a different TTI length. The order message comprises the number of TTIs after which a TTI switch has to occur, composed a.o. based on radio environment condition. The UE receives a TTI switch order message and replies with a single message to its serving BS with a message to switch the TTI in a synchronous way.

Abstract: The present invention relates to granting time intervals for transmitting a control signal burst and, more particularly, to methods and devices for granting Dedicated Physical Control Channel (DPCCH) bursts for Wideband Code Division Multiple Access (WCDMA). A base station determines whether a predetermined condition for transmitting a grant signal is satisfied and, if so, determines a schedule for receiving a control signal burst from a mobile device and transmits, in accordance with the determined schedule, the grant signal to at least said mobile device. Correspondingly, a mobile device transmits a report to a base station causing it to determine, in accordance with the report, a schedule for transmitting a control signal burst. Then the mobile device receives grant signals in accordance with the determined schedule and transmits a control signal burst in accordance with the grant signal.
